I should of bought some of this stuff much sooner. Its fantastic for full contact supports. Situations where surface finish and accuracy when using support are critical.However its extremely sensitive to humidity. You really need a dry box, and filament dryer for this stuff. To keep it in good working condition. Even more so if you live in an area with high humidity (like i do). If you do these two things, it should behave extremely well for you. With wonderful results. enclosed chamber is probably also a good idea. I haven't tried too use it on anything that doesn't have a fully enclosed print chamber.So far I have not needed to submerge my parts in water to remove the material. Since its about 80-90% humidity here most of the time. After its out of the print chamber 10-15 minutes in the open air, and I can usually separate and remove this PVA support. With my finger and a small spudger (just to start the separation).I will definitely be purchasing this again.
